Abstract
Section titled āAbstractāA study of diamond-like carbon coatings deposition has been carried out. The coatings were deposited on ceramic cutting tools. Vacuum-arc plasma has been used for deposition. Dependencies of the coatings microhardness and density on the tools bias voltage U are presented. The microhardness reaches 50 GPa at U =100 V. With increasing U and temperature it decreases to 15 GPa at U =500 V. Effect of the coatings on oxide ceramics properties was revealed. They were used for lathe turning of hardened steel. The tests proved a high efficiency of the coatings.
